Avalanche Campground has 6 first-come first-serve campsites. It is located adjacent to Avalanche Creek. Fishing is available in Avalanche Creek and in the Crystal River, which is 3 miles downstream. One of the major trailheads into the Maroon Bells-Snowmass Wilderness is located adjacent to the campground.
Avalanche campground is a gorgeous campground. There's no camping fee, however, the site is relatively small/has limited spaces so their first come first serve policy can be problematic in finding a spot. Bear proof storage boxes and fire pits are available for each space as well. For those without AWD/4WD vehicles I would use caution/advise against since the drive to get into the actual grounds requires a bit of off roading including crossing a creek.
Campground Campground is way up in a mountain, a beautiful drive and itself. The spaces are well-kept and far apart from each other. They also each have a bear proof Locker for your items. The river is just nearby, as are some wonderful hiking trails. There is a composting toilet system, never my favorite thing in the world, but it's as good as they get. I will definitely use this campsite again.
Nice remote campground with nice scenery. Pit toilets, water spigot, creek nearby.
